Serena spent $8.20 buying cupcake ingredients. At the school bake sale she charged $0.75 per cupcake. If she made a profit of $14.30, how many cupcakes did she sell?

What is the equation?
14.30 - 8.20 = 0.75c
8.20 + 0.75c = 14.30
0.75c - 8.20 = 14.30
14.30 - 0.75c = 8.20

Drew wants to wallpaper his bedroom. The room is 10 ft long, 12 ft wide, and 8 ft tall. How many square feet of wallpaper does he need? So I got this question wrong and is wondering how I can get 352 square feet as my answer since that is what my teacher got and I don't know she got that so can someone plz help explain.

Answers

Answer:

you have four walls. two of them 12*8 and the other two are 10*8 ( we used 8 in both because it's the height of the room). so it goes( 2*12*8)+(2*10*8) and it goes 352S

Step-by-step explanation:

let's say that walls A 12*8 and walls B 10*8. you have 4 walls ta wallpaper.

for walls A= 2*12*8=192

for walls B=2*10*12=160

in total, you need 160+192= 352 square feet of wallpaper

Answer:

Step-by-step explanation:

Hello!

Height of pyramid = 845 feet

Slant height = 856 feet

width = 175 feet

The surface area of a pyramid = The base area of the pyramid added to the area of the 4 triangles.

The volume of a pyramid = 1/3 base area * height

1 Triangle = 1/2 base * height

Triangle = 1/2 * 175 * 856 feet

1 Triangle Area = 74,900 feet

The area of 4 triangles = 299,600 feet

Now, the area of the base = is 175 * 175 feet

Base area = 30,625 feet

Surface area = 30,625 + 299,600 feet = 330,225 feet

Volume = 1/3 * Base area * height of pyramid

Volume = 1/3 * 30,625 feet squared * 845 feet

Volume = 1/3 * 25,878,125 feet cubed

Volume = 8,626,041.(6) feet cubed
